Where to Plant Blue Eyed Grass

Knowing where to plant blue eyed grass is important for its overall health. So when growing blue eyed grass, choose a partially sunny location. While the plant can grow in full sun, it performs best in low light situations. It is tolerant of any soil pH as long as it drains well. Blue eyed grass will thrive in moist to average garden soil. The plant is easy to propagate by dividing plantlets away from the parent plant. Break off or cut the rhizomes away from the main plant, including the slender foliage of the young plants that form at the base. Plant them as individual specimens for increased spring beauty. The clump will get large year by year but you can dig it up and cut it into sections for new plants. Divide the plant in late winter every two to three years and you will have a scattering of the pretty flowers across the landscape. In addition to propagation by division, the flowers will produce seed in spring. Seeds spread easily in gardens with adequate moisture.

Blue Eyed Grass Care

Growing blue eyed grass care isn't difficult. Allow the leaves to remain on the plant after the blooms fade in summer. This gives the foliage time to gather energy to store in the rhizomes for the following season's bloom. After they turn brown, cut them back to just above the crown. Mulch around the plants with organic material to provide nutrients and help protect the plants during freezing temperatures. In zones below 4 or where hard freezes last all winter, dig up the plant in fall and pot up in garden soil. Move the plant to a low light location where temperatures are above freezing. When soils are workable, replant in spring and enjoy blue eyed grass wildflowers until summer.
